No improvements really. I have added an indirection layer to the tcp 
callback API that allows to plug in layers between the application (e.g. 
HTTP server) and TCP. This is implemented simply by having other 'bio' 
callbacks for mbedTLS.

The downside of course is that TLS processing time is done in 
tcpip_thread, so it really depends on your overall application use 
whether you want to use this layer or sockets. Since mbedTLS allows 
registering the callbacks per ssl context, it should be possible to use 
both APIs at the same time.
